Gregory Hainaut b4c04ed00a gsdx-ogl: wipeout subroutine code
Code was completey bitrotten
Code was a partial test (and yet 500 lines already)
Shader is more and more complex and multithreading support greatly
reduce the cost of shader switch

Gregory Hainaut e245b27c97 gsdx-ogl-debug: allow to dump various ps shader
Nvidia allows to get the ASM of the shader of the compiled shader. It is useful
to check the performance.

It also allow me to compile most of shader code path for QA

Dump is enabled in linux replayer + debug_glsl_shader = 2

Gregory Hainaut 5565544ba6 gsdx-ogl: DATE with texture barrier
Much faster for small batch that write the alpha value. Code can
be enabled with accurate_date option.

Here a summary of all DATE possibilities:
1/ no overlap of primitive
    => texture barrier (pro no setup of stencil and single draw)

2/ alpha written
    => small batch => texture barrier (primitive by primitive). Done in N-primitive draw calls.
    (based on GL_ARB_texture_barrier)

    => bigger batch => compute the first good primitive, slow but only 2 draw calls.
    (based on GL_ARB_shader_image_load_store)

    => Otherwise there is the UserHacks_AlphaStencil but it is a hack!

3/ alpha written
    => full setup of stencil ( 2 draw calls)

easy to map GSdx dump output with the GL debugger :)

gregory.hainaut 3d7b86660a gsdx ogl: Enable by default advance DATE effect on nvidia (GL4 GPU)
Note: DATE is used for shadows (persona 3) and others effect

You can disable it when you disable gl image extension (override_GL_ARB_shader_image_load_store = 0)
You can also enable it on AMD too (set it to 1 this time) but no guarantee.

If you feel the extension is too slow, you can try disable some gl barrier (aka "damn the torpedo full steam ahead!").
It can be done with the option UserHacks_DateGL4 = 1. Otherwise just disable the extension.

Note: don't enable UserHacks_AlphaStencil in the same time. GL_ARB_shader_image_load_store is an alternative implementation.
Enabling both in the same time will lead to undefined (well surely wrong) behavior.

gregory.hainaut 84895eadd9 gsdx ogl: correct most of Z-depth issue
Best setting if you driver support GL_NV_depth_buffer_float => GL_NV_Depth = 1 & logz = 0
Otherwise => GL_NV_Depth = 0 & logz = 1

Explanation of the bug:
Dx z position ranges from 0.0f to 1.0f (FS ranges 0.0f to 1.0f)
GL z Position ranges from -1.0f to 1.0f (FS ranges 0.0f to 1.0f)

Why it sucks:
GS small depth value will be "mapped" to -1.0f. In others all small values will be 1.0f! Terrible lost
of accuraccy.

The GL_NV_depth_buffer_float extension allow to set the near plane as -1.0f.
So
"GL z Position ranges from -1.0f to 1.0f (FS ranges 0.0f to 1.0f)"
will become
"GL z Position ranges from -1.0f to 1.0f (FS ranges -1.0f to 1.0f)"
and therefore
"z posision [0.0f;1.0f] will map to FS [0.0f;1.0f]" as DX

Yes we just get back all precision lost previously :)
However you need hardware (intel?) and driver support (free driver?/gles?) :(

gregory.hainaut e01c6cd9ce gsdx ogl: the proof of concept commit
* GL_ARB_shader_subroutine for perf
fix for nvidia => add missing shader declaration. Nvidia got +4fps on colin3 :) 

For the moment only 2 PS parameters are supported. Code need to be extended to support others games that often
switch shader program (like xenosaga).
require GL4 class hardware and the option override_GL_ARB_shader_subroutine = 1
Note: strangely on AMD linux it is slower!

* GL_ARB_shader_image_load_store for accuraccy (Date)
Use a signed integer texture and reenable color buffer writing

Current status: Amagami_transparency.gs & P3_battle_shadows.gs are now working on Nvidia with a small perf impact.
Current implementation detail:
1/ setup the standard stencil as before
2/ on remaining pixel, draw once to compute first primitive that will write a fail alpha value.
3/ final draw based on primitive id of step 2

Note: I think we would get a bad behavior if depth test&mask are enabled on step 2/3
Note2: on my limited testcase the perf impact was on CPU. It would be possible to merge step1&2 to nullifying it (could 
even be faster actually), however it would require more GPU power.

Again require GL4 class hardware. And the option UserHacks_DateGL4 = 1

Card that support gs:

Note for dx: opengl 3.2 (maybe not gles) supports both flat interpolation
convention (GL_FIRST_VERTEX_CONVENTION or GL_LAST_VERTEX_CONVENTION).  It might
be possible to shuffle vertex index to put the last vertex in first position.

gregory.hainaut 0f603a98d5 gsdx ogl: Test the ARB_shader_subroutine GL4.0 extension
The idea was to replace shader program swith by pointer function calls inside
shaders.  At least parameters that are often changed between draw call. So far
I only ported atst and colclip. Unfortunately code is "slower" (on GSdx standalone).
For the moment keep the code but disabled.

If I understand well the validation of program is done in the "driver thread"
but the additional call are done in the overloaded MTGS thread. Apitrace
profiling shows faster GPU draw calls. Another possibility is that the driver still
need to validate the draw call because of others state change.

Here some stats on colin3 (90 frames):
without subroutine: UseProgram 125246
with subroutine: UseProgram 2906, subroutine 125945 => 3605 extra calls overhead (not
all parameters are ported to subroutine)

gregory.hainaut bd5f379044 gsdx ogl:
* uniform was wrongly set before the activation of the program (free driver only)
* Always use only 1 drawbuffer. Easier besides previous setup was wrong for convert:ps_main1

GLES trial (v3):
* add the cmake option GLES_API. Note library (libgles) are hardcoded for the moment
* Disable opengl check
* Disable gl_GetDebugMessageLogARB not supported!
* Emulate gl_DrawElementsBaseVertex, add manually the index offset (surely slow but work)
* Fix hundred of shader error (no implicit cast of integer to float...)
Unfortunately GLES doesn't support dual blending so no blend in hardware renderer. Otherwise it is fine

* replace vertex interface with block interface. It avoid to depends on the ARB_sso extension.
* disable geometry shader on Nvidia & Linux. Slower but better than a black screen !
* default logz to 1, avoid some glitches.

* Always require libegl for GSdx. You still need to select the API at compilation.

* Try harder to detect FGLRX driver on window
* various clean

Remain to fix the coordinate system for upscaling

* separate sampler and texture setup
* Always disable GL_SCISSOR_TEST before any cleaning to be sure the all pixels are reset
* properly set upscale_multiplier in the linux gui (was mixed with msaa). Unfortunately it is still broken...
* Fix EGL with GSopen1
* Use stdcall for function definition in the replay (avoid segmentation fault)
* Directly use gl_Position in shader instead of an extra user defined variable

* Emulate Geometry Shader from the CPU.
* add some option to override opengl extension detection
* redo shader interface (again) to compile on the free driver

SW renderer is now working on the free driver.

To test it on your linux box use this cmake option -DEGL_API=TRUE
Note: (need opengl 3.0) I test mesa 9.2 git

* Found a way to avoid crash in AMD driver. Skip the upload of small texture but rendering is wrong now...
